GEORGE SAMUEL BAKER AND GEORGE WILLIAM PER/KS. OF LONDON. ENGLAND.

- MACHINE FOR MOLDING CHOCOLATE AND THE LIKE.

To all whom it may concern:

Be it known that we, (ii-anion SAMUEL BAKER and GEORGE \VILLIAM PERKS, both subjects of the King, of England, residing at London, in England, have invented certain new and useful Improvements in Machines for Molding Chocolate and vthe Like, of which the following is a specification.

This invention, relates to machines for molding chocolate and the like and the object is primarily to provide a machine for the production of hollow chocolate eggs produced bv causing the chocolate to flow around the interior of a mold in such a manner that all parts ofthe mold are covered with a uniform layer or thickness of chocolate, this result being produced by mounting the molds in a series of clips carried by a rotatable drum which is also capable of 1on gitudinal rocking movements as hereinafter fully described, reference being made to the accompanying drawings in which- Figure 1 is a side elevation of the complete machine. Fig. 2 is an end view thereof with certain of the molds omitted for clearness of illustration, and Fig. 3 is a plan view.

The machine comprises the base 1 from which extend the standards 2, 3 and 4, the

two former supporting the necessary gearing and mechanism for o erating the machine as hereinafter describ and the latter being hollow throughout its length. Between the standards 3 and 4 is mounted. the drum 5 consisting ofsolid end members 6, 6 and two or more removable sheet metal peripheral sections 7 7 secured to said end members in any convenient manner. To the peripheral sections 7, 7 are permanently secured a plu' rality of clips 8 of any convenient construction, but preferably comprising two curved or cupped members having overlapping flanges 9 which are attached to the sections 7 as-by screws 10 or equivalents. The said clips are for the reception of the molds 12 which in the form illustrated are of two part construction divided and hinged along the major axis.

' To one of the end members is bolted a cone 13 the smaller end of which is traversed by a shaft 14, the outer end-of which is carried by a bearing block 14 mounted to have sliding movement within the standard 4 which is made hollow for this purpose. Wi hin the cone there also extends a second shaft 15 supported in bearin s 16 in the standards 2 p and 3 andalso by a urther bearing 17 at the Specification of Letters Patent. 1 Patented Jan. 25, 1910.

end of a bracket 17 extending from said standard The two shafts 1-1 and 15 are coupled together by a universal joint 18 so that rocking movement about said joint may be imparted to the drum 5 in either direction, as shown by the broken lines in Fig. 1, in the manner hereinafter described. At the upper part of the standards 2, 3 is mounted the shaft 19 carrying the fast and loose pnlleys :20 and 21 respectively,a fork 22 capable of operation by the handle 22 being provided as shown for shifting the driving belt (not shown) from one pulley to the other in the known manner. llponsaid shaft 19 is keyed a pinion 23 meshing with a spur wheel 2-1 on the shaft 15 whereby rotation is imparted to the drum Upon said shaft 15 is a pinion meshing with a spur wheel 26 carried by a shaft 27 mounted in the standards 2. On the extremity of the shaft27 outside the standard 1 is keyed a cam 28 having a groove 29 in which en ages a roller 330 rotatably mounted in a 1'0 31slidably carried in bearings 32, 32 extendin Erom he standard 1, said rod being provided with a perfokeyed to the shaft 19to permit of rotatin the drum 5 throu h the gears 23. 24 am shaft 15, universal oint 18 and sha t 14 when v required.

'The operation of the machine is as follows. Before or during continuous rotation of the drum 5 the molds 12 charged with.

chocolate of the desired consistency are placed in the clips 8 on the periphery of said drum and during such rotation the drum is also cansedto rock about the universal joint 18 in the manner previously indicated through the medium of the cam groove 29, roller 30, rod 31, lever 35, rod 39, block 14 and shaft. 14. The character of this rocking movement is dependent on the profile of the cam groove 29 and may be varied at will according to the size of the mold or other conditions by replacing the cam by one having a groove of the desired profile. In the case of the cam illustrated,

more particularly in Fig. 2, and with. the

' theinterior surfaces thereof.

1 between the drum and cam shafts 15 and 27 respectively, the following movements of the drum 5 may be produced, viz. 'one revolution with the drum inclined having one end thereof in its lowest position, one revolution and a half during which said drum is rocked to bring said end to its highest position, one revolution during which said drum remains with said end in its uppermost position and a further revolution and a half during which the drum is rocked to its initial position. It will thus be seen that the chocolate is caused to flow completely around and from end to end within the' tion and arrangement of parts hereinbefore described and illustrated since the same may be varied within limits determined by the following claims without departing from I the spirit of the invention.

What we claim as our invention and desire to secure by Letters Patent of the United States is 1. In a machine of the character described,

- the combination of a drum, means for the reception of molds on the periphery thereof, means for rotating said drum and means for imparting rocking movements thereto during such rotation.

2. In a machine of the character described, the combination of a drum comprising end members and removable peripheral sections,

. clips carried by saidsections for reception of molds, means for rotating said drum about its ,axis, andmeans for imparting symmetrical rocking movements thereto about a point at the center of said axis during such rotation.

3. In a machine of the character described, the combination of a drum, means on the periphery thereof for the reception of molds, a bipartiteshaft connected to said drum, means for imparting continuous rotary movement to said shaft, a universal joint at the junction of the shaft members, and

means for imparting oscillating movements to one member of the shaft during the rotation of the drum, for the purpose specified.

4. In a machine of the character described,

the combination of a drum comprising two end members and removable peripheral sec tions, clips carried by said sections for recption of molds, a conical member within the drum connected to one of said end members, a shaft traversing and connected to said latter end member, a second shaft traversing and connected to the other end member and said. conical member, a universal joint at the junction of said shafts, means for imparting j continuous rotary movement to said shafts and means for imparting oscillating move ments to said last named shaft about the aforesaid universal joint.

5. In a machine of the character described,

the combination of "a drum comprising end members and peripheral sections, clips secured to said sections for reception of molds, a bipartite shaft connected to said drum, a universal joint at the junction of said shaft members, means for imparting continuous rotation to said shaft, a cam shaft, a cam thereon, reducing gearing between the drum shaft and cam shaft, and a rocking lever operated by said cam adapted to impart oscillating movements to one of said shaft members about the universal joint.

6. In a machine of the character, described, the combination of a drum, comprising two end members and removable peripheral sections, clips permanently secured to said sections-for reception of molds, a cone within the drum connected to one of said end members, a bipartite shaft traversing and connected to the end members, a universal joint within the drum at the junction of the shaft members, a slidable bearingv carrying one end of one shaft member, a driving shaft, reducing gearing between the latter and the bipartite shaft, a cam shaft, a cam thereon. reducing gearing between the drum shaft and cam shaft, a rocking lever operated by said cam, and a connection between said lever and the aforesaid sliding bearing, substantially as described.

In witness whereof we have signed this specification in the presence of two wit- IIGSSGS.
